csdn加这个代码是用来刷流量的吗？每个页面都有 一打开cpu就飙升

<div style="display:none;">
	<img src="" onerror='setTimeout(function(){if(!/(csdn.net|iteye.com|baiducontent.com|googleusercontent.com|360webcache.com|sogoucdn.com|bingj.com|baidu.com)$/.test(window.location.hostname)){window.location.href="\x68\x74\x74\x70\x73\x3a\x2f\x2f\x77\x77\x77\x2e\x63\x73\x64\x6e\x2e\x6e\x65\x74"}},3000);'>
</div>

格式化以后是 setTimeout(function() { if (!/(csdn.net|iteye.com|baiducontent.com|googleusercontent.com|360webcache.com|sogoucdn.com|bingj.com|baidu.com)$/.test(window.location.hostname)) { window.location.href = “\x68\x74\x74\x70\x73\x3a\x2f\x2f\x77\x77\x77\x2e\x63\x73\x64\x6e\x2e\x6e\x65\x74” } }, 3000); 这一串字节序列 对应的字符串是 csdn的网址
